I think that any guitar player would love to take lessons from Slash or Dave Navarro and now they can with the magic of the internet. Advanced guitar lessons on the internet are not only free but they feature some of the best guitar players in the business. On a recent clip on www.youtube.com, Dave Navarro, former lead guitarist of the Red Hot Chili Peppers joins George Lynch, guitar god from Lynch Mob in showing some advanced guitar lessons for the general public. Navarro has an online show called Spread TV and he has different guests each week from the rock and roll world. With George Lynch they discuss intricate guitar licks and different techniques.
In another episode of Spread TV, also available on www.youtube.com, Dave Mustaine, the great guitar player for Mettalica, shows Dave how to play spider chords. Spider chords were invented by Dave Mustaine (or so he claims) and he has used them in bands like Metallica and Megadeath to great effect and to create some of the most memorable licks of all time.
There is a great clip available on youtube featuring the great Neal Schon of Journey fame teaching how to play the great song Lights. For advanced guitar lessons this one is great because it shows close ups of his fingering technique on the guitar neck. The bad part is that he does not stop and explain the parts. If you are a very advanced player you will not have much trouble copying his moves, but it would still be helpful to hear some commentary, even if it is just a little. A lot of these guitar guys dont like to explain their moves and many of the clips are like this.
There are some great Slash (Guns n Roses) clips available on www.youtube.com. One of the best instructional videos is a very short clip where he shows (not teaches) how to play the intro to Paradise City, one of Guns n Roses biggest international hits. There are lots more famous guitar players on youtube but you have to search through a lot of junk in order to find them. If you are persistent you will find some gems though, like the guitar player from the Red Hot Chili Peppers who has posted lots of advanced guitar lessons of his own on there.
The very talented guitar player John Mayer shows how to play some great riffs on his video show sponsored by Guitar World, How to Shred. There is also a great video on there by the legendary jazz guitarist Larry Carlton, who has recorded with greats such as Steely Dan and many others.
For advanced guitar lessons there are some great DVDs available as well and you can get those online or at your local Guitar Center store or your local music supply store.
